These are the changes that need to be made if a computer is to be added to the CS network, follow these steps.

Software

Make sure the following packages installed (through ports or through apt):

  • bash
  • ssh
  • sudo

SSH and Sudo

  • Set up sudo to allow members of the admin group to become root (or, better yet, individual users).
  • Disable root logins via SSH.

DNS and DHCP

DNS

  1. ssh tinydns.cs.earlham.edu
  2. Find an available IP in /service/tinydns/root/data
  3. Add a line to that file:
=<hostname>.cs.earlham.edu:<ip>:86400
  1. cd /service/tinydns/root/ && make

DHCP

  • Add the machine to forty-one:/etc/dhcp3/dhcpd.conf. You will need its Ethernet MAC address for this. Make sure to terminate each field with a semicolon.
    • Restart dhcpd by running the command /etc/init.d/dhcp3-server restart

Email

  • In /etc/aliases or similar, set the outgoing e-mail to root@cs.earlham.edu. On quark, this automatically forwards to the admin list. We send it to root instead so that we can have "emergency moderation" and stop it going to the list if need be. Or, in case we need to stop going to the list because mailman is down.
